# CHANGELOG

## alpha10-layout-rollback
- Restored the last non-broken slide workspace layout from alpha1.
- Kept UnifiedSlide naming.
- Removed root index.html; demo is under demo/basic.html.
- Kept v1.6 package metadata.


## alpha11-demo-runtime-fix
- Fixed demo/basic.html theme CSS paths to ../themes/base/*.css.
- Ensured JSZip loads before pptxgenjs to avoid JSZip is not defined.


## alpha12-jszip-global-fix
- Fixed pptxgenjs runtime error `JSZip is not defined` by preloading JSZip before RequireJS and adding an AMD wrapper at `scripts/vendor/jszip_wrapper.js`.
- Kept the alpha1-based stable workspace layout unchanged.


## alpha13 - initial render / toolbar / ruler fix
- Fixed first display race that caused the slide canvas to appear blank until the thumbnail was clicked.
- Restored visible top ruler and left ruler alignment around the canvas.
- Hid advanced/low-frequency toolbar commands behind the More button by default.
- Kept the stable alpha12 workspace layout and JSZip global fix.


## alpha14 - Unified PPTX Writer foundation

- Removed default PptxGenJS loading from the runtime dependency chain.

- PPTX export now generates the package directly from UnifiedSlide.
- Added documentation for the new export architecture.

## alpha15 - Control Framework foundation

- File menu now exposes storage-neutral commands: New, Open, Save, Save As, Import, Properties, and Export.
- Open, Save, Save As, Import, Export, and Insert Image now call the Host/Demo `OpenFile` / `SaveFile` callback contract.
- Save As uses the selected file extension to resolve `.usldx`, `.png`, `.pdf`, or `.pptx` output generation.
- Insert Image is treated as `OpenFile({ operation:'open', role:'asset' })`.
- Added icons to menu items.
- Added demo-local callback implementation in `demo/basic.html`; product runtime remains storage-neutral.

## alpha17 - demo-policy

- Added Demo categories, purpose, expected checks, required callback notes, and direct open actions.
- Added client-side detail switching so Host integration reviewers can understand each demo before opening it.
- Kept all Demo-only UI and CSS under `demo/`; no root-level `index.html` is provided.


## alpha20 Demo frame maximize fix
- parameters.html now performs true fixed-position Control frame maximization and restore.
- Demo-only maximize logic remains under demo/assets/js and demo/assets/css.
- Embedded workspace receives resize notifications after maximize/restore so rulers and canvas layout refresh.

- Preserved alpha20 Demo maximize behavior and stable slide workspace layout.

## alpha22 - i18n demo/runtime
- Parameters Demo and Basic workspace now apply Host language option.
- Japanese/English/Chinese labels are provided for Demo frame, menu, panels, status bar, context menu, and slide placeholders.

## alpha36-script-pptm-core

- Added browser-safe UnifiedSlide Script runtime services.

- Added VBA analyzer and practical PowerPoint VBA subset converter.

## alpha36-fix1-pptx-import-dialog

- Reconnected `.pptx` / `.pptm` import to the current callback runtime.
- Added `scripts/services/pptx/pptx_import_service.js` as an app dependency before `scripts/app.js`.

- Scoped runtime CSS under `.uslide`; removed package runtime `app.css` / `theme.css` generic names.
- Added `openFile`, `saveFile`, `saveAsFile`, `exportFile`, and `getFileContext` Programable Editing Control API.
- Updated Demo callbacks to accept `HostSavePayload/v1.payload.data`.


## alpha36-fix12-floating-ui-hidden-fix
- Fixed the Basic Demo startup overlay regression where the Presentation overlay was visible even when the `hidden` attribute was present.
- Added the package overlay class `uslide-floating-ui` to body-level overlays and context menus that are intentionally outside the `.uslide` root.
- Added scoped floating UI CSS for `.uslide-floating-ui` so v1.10 CSS scoping remains compliant without relying on generic body/html selectors.
